Mercedes AMG GT Concept

The Mercedes AMG GT will have a 4.0-litre V8 engine partnered with an electric motor; up to 600kW (804hp) with a 0-100 km/h time of less than three seconds. There's more to this hybrid system than sheer speed, too. The energy storage unit is said to be lighter, smaller and more powerful than normal batteries, while also being modular. The car signals a Porsche Panamera-type machine with a long roof. The rear curvaceous rear end is styled with slit taillights and a rotundity reminiscent of the AMG GT.
If it's more than a concept and actually enters production, expect the price tag to be well over $100,000.
